Claude Code with GitHub Enterprise Server changedgithub-enterprise-server

Nearest release: v2.1.285, published 9 hours before upstream edited the page. Shown because the two are within 24 hours of each other. Nothing here says the release caused the edit.

Upstream edited this page at 30 Sep 2026 03:00 UTC, give or take a minute or two: the time comes from Anthropic’s own sitemap rather than from a commit. This site recorded the change at 30 Sep 2026 03:07 UTC.

8282### Network requirements

84For Anthropic-hosted sessions, your GHES instance must be reachable from Anthropic infrastructure so Claude can clone repositories and post review comments. If your GHES instance is behind a firewall, allowlist Anthropic's [outbound IP addresses](https://platform.claude.com/docs/en/api/ip-addresses#outbound-ip-addresses). Sessions in a [self-hosted environment](/docs/en/self-hosted-environments-deploy#configure-git) clone from inside your network instead, unless the runner opts into the [Anthropic git proxy](/docs/en/self-hosted-environments-deploy#use-the-anthropic-git-proxy), which fetches from Anthropic's side and needs the same reachability; the [SCM connector](/docs/en/self-hosted-environments-reference#scm-connector-flags) covers the hosted pre-session flows, such as the repository picker, for a GHES host that's only routable internally.

86Hosted pre-session flows, such as the repository picker, run on Anthropic's side before a session starts. They need your GHES instance to be reachable from Anthropic infrastructure even when the session runs in a self-hosted environment. The [SCM connector](/docs/en/self-hosted-environments-reference#scm-connector-flags) isn't available, so those flows can't reach a GHES host that's only routable internally.

8688## Developer workflow

8890Once an Owner has connected the GHES instance, no developer-side configuration is needed. Claude Code detects your GHES hostname automatically from the git remote in your working directory.

211If reviews or Anthropic-hosted cloud sessions time out, your GHES instance may not be reachable from Anthropic infrastructure. Confirm your firewall allows inbound connections from Anthropic's [outbound IP addresses](https://platform.claude.com/docs/en/api/ip-addresses#outbound-ip-addresses). Sessions in a [self-hosted environment](/docs/en/self-hosted-environments) reach GHES from inside your network, so for them check the runner's own network path and the [SCM connector](/docs/en/self-hosted-environments-reference#scm-connector-flags) instead.

For the repository picker and other hosted pre-session flows, see [Network requirements](#network-requirements).
